Write Mode — This bit controls the write mode for this register.
0 update SEL and RSBIDX field on register write
1 update only SEL field on register write
Selector — This field is used to select the internal receive shadow buffer index register for access.
00 RSBIR_A1 — receive shadow buffer index register for channel A, segment 1
01 RSBIR_A2 — receive shadow buffer index register for channel A, segment 2
10 RSBIR_B1 — receive shadow buffer index register for channel B, segment 1
11 RSBIR_B2 — receive shadow buffer index register for channel B, segment 2
Receive Shadow Buffer Index — This field contains the current index of the message buffer header field of the
receive shadow message buffer selected by the SEL field. The FlexRay module uses this index to determine the
physical location of the shadow buffer header field in the FlexRay memory. The FlexRay module will update this
field during receive operation.The application provides initial message buffer header index value in the
configuration phase.
FlexRay module: Updates the message buffer header index after successful reception.
Application: Provides initial message buffer header index.
Receive Shadow Buffer Index Register (RSBIR)
Media Access Test Symbol Transmission Enable — This control bit is used to enable and disable the
transmission of the Media Access Test Symbol in the selected set of cycles.
0 MTS transmission disabled
1 MTS transmission enabled
Cycle Counter Mask — This field provides the filter mask for the MTS cycle count filter.
Cycle Counter Value — This field provides the filter value for the MTS cycle count filter.
